Two artists went home as a consequence of the judges' decision to save Michael Lynche at the end of last week's results show.
Garcia seemingly failed to recapture the magic of his Hollywood Week acoustic performance of Paula Abdul's 'Straight Up'.
"It's like the coolness has been sucked out of you," judge Simon Cowell told him after last night's performance.
While the rest of the panellists praised Stevens's selection, Cowell found it "annoying" and the voters listened.
Tonight's programme also included a duet from Brooke White and Justin Gaston, as well as a performance from Idol runner-up Adam Lambert.
